Our New Metrics

To measure the effectiveness of this eco-friendly data centre roadmap, existing metrics (like PUE, CUE and WUE) are complemented with new ones able to better capture the relation of amount of services delivered by a data centre with respect to the consumed energy (Software Execution Energy Efficiency), and other ones measuring the effective utilization of available renewable energy (Renewable Energy Utilization Efficiency); specific benchmarks are researched to support the measurement of energy efficacy and allow comparisons of results among different data centres. The natural follow-up of this research stream is DC4Cities active participation to standardization bodies to promote these new metrics. The figure provides a high level view of these new metrics
